Can dogs eat crab shells?

Dogs should not eat crab shells. Crab shells are very sharp, hard and thin, so if you bite into them and swallow them, you can easily cut your dog’s intestines and stomach, causing bleeding. There is no need to give your dog crab shells because they have no nutritional value. Remember to clean up the residue after the owner has eaten the crab. You can give your dog a little bit of crab meat, but don’t feed him too much, and don’t give him crab meat for a long time, otherwise it will easily prevent the absorption of vitamin B1 and lead to neuritis.
